S ICKLE GUARD APPLIANCE Fled Aug. 22, 1939 Inventer Z7Mer Patented Feb. 17, 1942 UNITED STTES A NT OFFICE 3 Claims.

This invention appertains to new and useful improvements in agricultural machines and more particularly t a sickie guard attachment.

The principal object of this invention is to provide an appliance of the character stated which can beeasily applied to sick1e guard teeth and which will remain in place under all and varying conditions.

Another object of the invention is to provide an appliance of the character stated in which the parts are constructed t0 permit a wide range of adjustability and adaptability to the conditions under which it must operate.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawing:

Figure 1 is a side elevational view of one of the tines.

Figure 2 is a side elevational view.

Figure 3 is a top plan view of the structure shown in Figure 2.

Referring to the drawing wherein 1ike numerals designate like parts it can be seen that numeral 56 denotes a tine which consists of the straight portion (1, the slightly inclined forward portion D and the backwardly disposed straight portion c which terminates just above the sickle assembly Il. This structure is clearly shown in Figure 1.

Figures 2 and 3 show means for clamping one of these tines 52 directly to a toothed guard and in this case the clamping means consists of a pair of members 1l and 12 the member Il engaging the underside of the member 10 and having side parts extending up the sides of the guard 10 and a plate 13 extends rearwardly from the member H and has a hole therein for receiving a bolt 14 depending from the rear end of the guard 10 and forming part of the means for connecting the guard to the cutter assembly of the machine. The member H is formed with depending gripping jaws 15 for receiving an end portion of the tine and these jaws are caused to grip the said end portion by the bolt 16. The member 12 is made in the form of a pointed cap and fits over the pointed end of the guard and a portion of the front end of the member Il. This member 12 is formed with the jaw parts 11 through which a boit 18 passes so that by tightning the bolt these parts 11 will g rip an0ther portion of the tine 52 and thus the tine is' clamped to the guard 10 by the' clamping means Il and 12 as shown in Figures 2 and 3.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:

1. A lifting finger attachment for sickie guard teeth comprising a hollow cup1ike structure adapted to embrace the 1ead end of a guard tooth and being split at its lower portion and formed t0 define a pair of jaw members, contracting means between the jaw members, an elongated tine extending longitudinally through the cup-like structure and adapted to be clamped in position by the jaws, and anchoring means for anchoring the rear portion of the tine to a guard tooth.

2. A lifting finger attachment for sickie guard teeth comprising a hollow cup-like structure adapted to embrace the 1ead end of a guard tooth and being split at its lower portion and formed to define a pair of jaw members, contracting means between the jaw members, an elongated tine extending longitudinally through the cup-iike structure and adapted to be clamped in position by the jaws, and anchoring means for anchoring the rear portion of the tine to a guard tooth, said anchoring means consisting of a pair of side members adapted to extend Iongitudinally and engage opposite sides of a guard tooth, the forward end portions of the side members extending into the cup-like structure, and contractihg means between the rear portions of the side members for contracting portions of the said side members agaihst the rear portion of the tine.

3. An attachment for sickie guard teeth comprising a cup-like member adapted to receive the forward end of a guard tooth, a tine extending through the cup-like structure and forwardly invention, what is thereof, said cup-like structure being provided with contractible means for clamping the tine against movement through the cup1ike structure.
